Latest Ice core Stories
Polarstern, a research icebreaker, returned from the South Pacific in 2010 with a scientific treasure. The treasure, described in a recent issue of Science, consisted of ocean sediments from a previously almost unexplored part of the South Polar Sea.
An international team of glaciologists, led by Ohio State University, has discovered new and compelling evidence that the Italian Alps are warming at an unprecedented rate. The discovery was made less than 20 miles from the site where melting ice exposed the 5,000-year-old body of Ötzi the Iceman.
One of the deepest ice cores ever drilled in Antarctica is revealing some interesting evidence about the southern continent’s turbulent past and the role Earth’s orbit played in the history of the ice ages.
How severely have volcanoes contaminated the atmosphere with sulfur particles in past millennia?
Lake Vostok, the largest of some 400 subglacial lakes scattering Antarctica’s frozen world, has been the subject of research for at least the past 15 years. Lying more than 2 miles below the surface, the lake was first drilled in 1998 by a team of Russian, French and American scientists.
An international team of scientists, led by Julie Brigham-Grette of the University of Amherst, has analyzed the longest continental sediment core ever collected in the Arctic to provide “absolutely new knowledge” of Arctic climate from 2.2 million to 3.6 million years ago.
A new 1000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost ten-fold, and mostly since the mid 20th Century.
According to a new study, the dramatic glacial melt in Western Antarctica is due to natural variation and cannot be attributed directly to carbon emissions.
Earth's tropical climate history has been revealed in unprecedented detail – year by year, for almost 1,800 years – by two annually dated ice cores drawn from the tropical Peruvian Andes.
Not cleaning a kitty’s litter box could be a disgusting thought for cat owners, but for Brian Chase of Montpellier University in France — layers of dried urine can reveal exciting new details about an environment as they stack up year after year and generation after generation.
